📎CO2 sensor calibration

TX CO2 COV T&H AMB 600-023/ TX CO2 T&H AMB 600-123

The TX CO2 VOC T&H AMB 600-023 sensors are delivered pre-calibrated.

You can re-calibrate them manually on a “fresh-air” basis if you notice a shift in the CO2 values ​​measured over time. To ensure the best possible calibration, we recommend that you calibrate the products by following the procedure below:

1. When the sensor is powered, position it on a table near a window, the window must be open so that the air in which the transmitter will calibrate is healthy.

1. Press the push button located on the transmitter electronic board for 15 seconds. Only release the pressure when LEDs L1, L2, L3 light up. This means that the calibration process has been activated.

1. Walk away from the sensor and let the calibration take place. The process takes approximately 3 minutes.

1. When the LEDs stop flashing, this means that the calibration is complete. You can take the sensor and install it in its final location.

We recommend that you press the push button using a screwdriver or pen so as not to damage the CO2 sensor with your finger.
